Sure lots of heat pumps can “heat” that low, you’re not getting very much heat though. I’d be surprised if they don’t have some kind of supplemental heat source. I didn’t see any actual engineering documents to see what the outputs are at those ranges. To heat a space you should have output temps minimally in the low 90F range. Some of the heat pumps now are heating the refrigerant seperately in those low temp conditions. So kind of cheating.
